Soft, breathable, and lightweight, the Nike Sport Loop is designed for fitness, with select colors matched to the new line of Nike running shoes. It features a hook-and-loop fastener for quick and easy adjustment and a double-layer nylon weave with dense loops on the skin side that provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability. Like all Apple Watch bands, you can match this band with any Apple Watch case of the same size.
